The results show that coal and gangue are involved in the microbial role; the quantity of inoculums is directly related to the quantities of gas and the contents of methane, at the same time it has a certain degree of impact on the contents of NO(superscript - subscript 3)-N, NH(superscript + subscript 4)-N, S(superscript 2-), SO(superscript 2- subscript 4), and metals; moreover, because of the microbial anaerobic fermentation, the contents of NH(superscript + subscript 3) are seriously substandard; overall, the group B which has a smaller proportion of gangue has a less impact to the environment compared to the group A which has a larger proportion of gangue.

Using mordern physical chemistry techniques (such as XRD、 TG-DTA、 IR、 XPS and 〓Xe-NMR)、 chemical adsorption techniques (NH〓-TPD、 H〓-TPD、 TPO、 TPR etc.) and pulse flow microreaction of n-hexane、 methylcyclopentene and n-hexane containing 0.2ppm thiophene, we studied mainly the following three points:(1). the changes occured during the calcination pretreatment of Pt ammine complex supported on β and L zeolites;(2). the effect of structure and acidity-basicity of zeolite on the dispersion and electron state of Pt particles; and (3). the influence of second metal component on the reactivity of nhexane aromatization and sulphur-resistance of Pt/L zeolite catalyst. Several interesting and valuable results are obtained and summerized as follows

本论文运用各种近代物理表征方法(XRD、BET、TG-DTA、IR、XPS和〓Xe-NMR)、化学吸附技术(NH〓-TPD、H〓-TPD、TPO、TPR等)和正己烷、甲基环戊烷及含噻吩正己烷的脉冲微反等方法，着重研究了(1)载Pt的β和L沸石在分解预处理过程中发生的变化；(2)沸石载体结构及酸碱性对Pt粒子分散及电子状态的影响；(3)第二金属组份对载Pt沸石催化剂上正己烷芳构化及抗硫性能的影响等，得到了某些有意义的结果。

The pH value in soil was significantly increased in litter aqueous extract of four decomposition stages. The NH+4-N concentration was significantly decreased in soil amended with litter aqueous extract of 10-day decomposition which promoted the growth of Aerobic azotobacter and Ammonifier but inhibited the growth of Aerobic cellulose-decomposer. Available phosphorus concentration was significantly increased and phenolic acid content was significantly decreased in soil amended with litter aqueous extract of 60-day decomposition which inhibited the growth of Aerobic azotobacter but promoted the growth of Aerobic cellulose-decomposer.

不同分解时间的凋落物浸提液均造成了土壤pH值的显著升高；分解10d的凋落物浸提液对土壤铵态氮的含量具有显著的降低作用，对土壤好气性自生固氮菌和氨化细菌的生长均具有显著的促进作用，而对好气性纤维素分解菌的生长具有抑制作用；分解60d的凋落物浸提液显著地降低了土壤酚酸含量，对土壤有效磷含量具有显著的升高作用，对好气性自生固氮菌的生长具有抑制作用，而对好气性纤维素分解菌的生长具有促进作用。

The change of remaining litter weight was the largest in the earlier 30 days during 60-day litter decomposition, and there was no significant difference in subsequent 30 days. The phenolic acid content of litter was significantly reduced with the decomposition time prolonging, and the releasing quantity of phenolic acid was the highest at the tenth day. The amounts of soil Aerobic azotobacter, Ammonifier and Aerobic cellulose-decomposer and the soil chemical properties such as pH, phenolic acid content, NH+4-N and available phosphorus were significantly affected by the litter aqueous extract of four decomposition stages.

凋落物分解的60d中，凋落物残留量在前30d内变化最大，30d后无显著变化；凋落物中酚酸含量随分解时间的延长，呈显著降低的趋势，且在分解10d时，酚酸释放量最大。4个分解动态的凋落物浸提液显著地改变了土壤好气性自生固氮菌、氨化细菌、好气性纤维素分解菌的数量和土壤pH值、酚酸含量、铵态氮、有效磷等化学性质。
